.2 Claims.

This invention relates toatomizers and more particularly to new anduseful improvements in pocket size atomizer construction.

An object'of the invention is to provide a pocket size atomizer havingthefewest possible parts, including a one-piece block member havingvarious openings drilled therein in such relationship that a plungerdisposed in one: of'the openings will cause atomization of liquidcontained in another of'the' openings;

Another object is to provide a pocket size atomizer that" is leak'proof; attractive in design, easy to assemble an'd'can withstand longusage without requiring servicing.

These and other objects'are accomplished in brief, by providing anatomizer that has a block member that can be made from a solid block ofmaterial by drilling thereina well, a well air vent, a hole to the welladapted 'to admit a tube, an air compression chamber and an airpassageway extending from a vent above the hole to the compressionchamber. A tube is disposed in the hole with a portion extending intothe well and a nozzle projecting from the block to a positionedjacentthe air passageway Vent. The bottom of the Well is closed b a threadedplug, and a spring impelled plunger isslidably disposed withinthe aircompression. chamber and is adapted to force air through the airpassageway and its vent to cause atomizationoflliquid from within thewell.

For further comprehension of the invention, andof the objectsandadvantages thereof, reference will behad to-the: following descriptionand-accompanyingdrawings andto the appended claims in whichithevariousnovel-features of the invention are more particularly set forth;

In the accompanying drawingsforming a-materialpart of this disclosure:

Fig; '7 is a perspective "view of the top portion of the atomizer'.

In the drawings and "in the specification, in which like: referencenumbers designate similar parts, a pocket atomizer-Jonas a block memberll, preferably of aluminum or other light metal, said blockbeing-shaped? with a fiat bottom face 12 and a stepped top having atopmost face l3, a middle top face;ilandra-lowermost topfacelfi.

The block H has-acylindrical air compression chamber l6extending-downwardly from its topmost face I -3'to a'conical-terminus lladjacent its bottom face l2, andia cylindricalwell lilextendingupwardly-fromitsbottom face l2 to a conical terminus" [9- below itsstepped top faces. The mouth 20- of thewell I 8" at the bottom of theblock I I is threaded, and a threadedeplug 2'! is engaged therewith tocloseflth'e well at its bottom. A hole 22 extends downwardly from thelowermost top face l5 of the block tothe'well conical" terminus l9, anda tube 28 extends through the hole 22 with a reduced nozzle [Aprojecting upwardly from the lowermost top face l5 and a tubeportion 25disposed within the well, the endof the tube within the well: beingslightly above the threaded plug 2| so that liquid in the well canreadily enter the tube: A wellair vent 26 extends downwardly from themiddle 'top face [4 of the block to the well conical terminus l9.

A cylindrical passageway?! extends upwardly from the bottom face =1ziofthe block betweenthe air compression chamber l6 and the well l8,said passagewa rising to about the sam elevation as the conical terminusof the well, and another cylindrical inclined passageway 28 extendsupwardly and laterally from the upper end of the passageway Z'Itoa vent29in a'vertical face '30 connecting the middle top face t4 andthelowermost top face .15; The'venttll and the tube'nozzle 24 are adjacenteach other, and 50 positioned as to cause atomization: of liquid withinthe well when air is forced outwardly through the vent. A plug 3|permanently'seals'thelower end of the passageway 21, and an aperture 32extends'between the passageway 21* just above the plug'and the conicalterminus l"! of the air compression chamber. Thus; 'a continuous airpassageway is formed leading from'the compression chamber, through theaperture 32', up the vertical passageway 21, through" the inclinedpassageway 28 and out through thevent 29, the permanent plug 31sealing'the bottom of 'the'passageway 2'1 and forcing the air from the?compression chamber to follow the course outlined.

The relative positioning of the well, chamber, passageways,holes,'ventszand. apertures" is of the utmost importance; since :theyhave beendesigned to permit the atomizer block to be made from a solid bock of material allowing many of the drilling, boring and reamingoperations to be performed simultaneously or consecutively on piecesheld in a jig or fixture. Thus, with the bottom face of a block exposed,the we l and the passageway 21 can be bored and drilled and the wellmouth threaded, and with the top face of the block uppermost, the airchamber, the tube hole 22, the Well air vent 26, the passagewa 28, andthe aperture 32 can be bored and drilled. With the block thus formed,the tube 23 can then be force fed in the hole 22 to the position shownin the drawings and described hereinabove.

A collar 33 is disposed within the air compression chamber l5 below thetopmost face I3 of the block, said colar having an air intake 34 and aconcentric opening 35 therethrough. A plunger assembly 36, consisting ofa plunger stem 31, a rubber gasket 38, gasket seat 38', washer 39, aspring 40 and a nut 4|, is positioned with the plunger stem 31 extendingslidably through the opening 35' of the collar 33, the

gasket 3.8 threaded on the lower end of the stem between the gasket seat38' and the washer 39,

the spring 40 located within chamber [6 between the gasket and conicalterminus I1 and acting to force the plunger upwardly and the nut 4| gaskt and washer securel in position. The plunger stem 31 has an enlargedend 42 which engages the colar 33 when the plunger is fully depressed,leaving a domed top portion of the end 42 ext nding somewhat above thetopmost face I3 of the block.

The atomizer I!) is provided with a pivotally mounted top portion 43(see Figs. 1 and '7) which is formed with a cover 44 having front andback parallel edges 5, a curved edge 46 extending 'between the edges 45,a flange 41 extending downwardly from the edges 45 and 46, and twocut-out portions 48 extending inwardly from its remaining edge 49leaving a center tongue 50 therebetween.

The top portion 43 is rotatably joined to the block II by means of a pin5! which extends through two opnosing holes 52 in the flange 41 and ahole 53 which extends transvers ly through the stepped top of the block.The stepped top of the block is set s ightly in at sides 54 so that thecover 44 is flush with the topmost face I3 and the flange 41 is flushwith the front and back faces of the block, while the tongue 50 rests ina slotl55 in the to most face I3. In closed position, the undersurfaoeof the cover 44 seals the tube nozzle 24 and the well air vent 26preventing leakage of liquid from the well.

The enlarged end 42 is provided about its o ter ripher with a groove 42hich ton ue 50 engages while the atomizer is in inoperative position.

When it is desired to use the atomizer of the present invention, it isnecessary first to release plunger 36 by pressing inwardly on end 42.This causes top portion 43 to rotate on pin 5| thus disengaging tongue50 from groove 42' and permitting plunger 36 to spring upwardly due tothe force of spring 40. Now each time the plunger is pressed downwardlythe air within chamber [6 becomes compressed, is forced out throughaperture 32, passageways 2! and 28 and .out through vent 29, thusproducing a change in atmospheric pressure in tube 23 and resulting inthe rise of liquid within the tube due to the threaded on the stem toretain the 4 aspirating action thus brought about. At the same time, theliquid so raised is formed into a fine spray by the air which escapesthrough vent 29.

5 If it is desired, the well air vent 26 can extend from the well to aterminus in any face of the block, and a tiny one way air valve disposedtherein to permit air to enter the well.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reversed to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:
